Coding or comprehension? The essence of software system design
(University of Hertfordshire, 1993)
Throughout the disciplines of engineering, modelling and simulation are generally considered as important components of any modern designer's tool kit. They allow the powerful mechanisms of abstraction, decomposition and ...
Modelling superscalar pipelines with finite state machines
(University of Hertfordshire, 1993)
We are currently examining the use of Finite State Machines to model processor pipelines. Our aim is to discover the extent to which the complexities of modern superscalar pipelines are amenable to theoretical modelling. ...
Training Kohonen feature maps in different topologies: an analysis using genetic algorithms
(Morgan Kaufmann Publishers Inc., 1993)
An evaluation of the architectural features of the iHARP processor
(University of Hertfordshire, 1993)
RISC processors have approached an execution rate of one instruction per cycle by using pipelining to speed up execution. However, to achieve an execution rate of more than one instruction per cycle requires multiple ...
Process simulation for waste management
(1993)
A critical assessment of available options for waste separation, recycling and energy recovery is an essential strategic step in formulating an economic and technically viable waste management policy The underpinning data ...
An evaluation of the HARP ORed indexing addressing mechanism
(University of Hertfordshire, 1993)
Several different adressing mechanisms are evaluated within the context of VLIW and superscalar processor design. The results suggest that traditional RISC addressing mechanisms are less effective than the other simpler ...
Positive fixed points of lattices under semigroups of positive linear operators
(University of Hertfordshire, 1993)
Let Z be a Banach lattice endowed with positive cone C and an order-continuous norm [...]. Let G be a semigroup of positive linear endomorphisms of Z. We seek conditions on G sufficient to ensure that the positive fixed ...
H2 Spectroscopy in the Photodissociation Region of M17 Northern Bar
(Astronomical Society of the Pacific, 1993)
We present results of long slit spectroscopy, from 2.0 to 2.5 microns, of the photodissociation region in the northern bar of M17. The observations give us an insight into the physical conditions in the region and provide ...
Self defence in open systems using self authenticating proxies
(University of Hertfordshire, 1993)
Most of the methods currently used to protect both users and systems and their objects and servers, involve authentication of principals and access control of these objects and servers. Authentication and access control ...
Decomposing the corpus of neuropsychological tests
(1993)
This commentary has had two primary concerns: We have attempted to address the difficulties and possibilities of using cognitive tests to measure the underlying biological basis for mental disorders. In particular, we have ...
